Twice the sum of a number and negative three is ten. Find the number. Round your answer to the nearest integer, if necessary.
The number is

x=8

Step-by-step explanation:

2(x-3)=10

2x-6=10

+6

2x=16

/2

x=8

x=8

Step-by-step explanation:

The equation is:

2(x + -3) =10

x=8

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
